Ketones Production by Catalytic Pyrolysis of Cellulose Using Iron-Modified Ni-Co Composite Catalyst: Products Distribution, Behaviour and Bio-oil Characteristics

Pyrolysis of Seaweeds for Bio-oil and Bio-char Production

A pyrolysis study on a species of brown algae Saccharina japonica was carried out in a fixed-bed reactor. The yields of bio-oil and bio-char obtained at 450 C were 47 % and 33 %, respectively. The raw S, japonica, ethanol and acid pretreated samples and the resulting pyrolysis products were also characterized with respect to proximate and ultimate analysis, and higher heating value. The crude b...

Co-Production of Activated Carbon and Bio-Oil from Agricultural Residues by Molten Salt Pyrolysis

The feasibility of co-producing activated carbon and bio-oil from rice stalk through molten salt pyrolysis is reported in this work. The results indicated that: (1) mixed ZnCl2-KCl molten salt could considerably improve the solid and liquid yield as well as the ratio of H2 and CH4 selectively (compared to the traditional ZnCl2 method), (2) an increase of pyrolysis temperature had the same impac...

Catalyst-assisted Conversion of Pyrolysis Bio-oil into Fuels

The aldol condensation of model compounds furfural and acetone on the selected base catalysts have been performed. The activity of MgO was compared with industrially produced hydrotalcite and the series laboratory prepared hydrotalcites. Si×MAl2O4 hydrotalcites (M = Mg, Zn, Ni, Co, Cu, and Fe) were prepared by the solgel method at low calcination temperature of 300°C. The properties of the cata...

Biofuel Production and Kinetics Study of Catalytic Microwave Pyrolysis of Douglas Fir Pellet over Activated Carbon Supported Metal Catalyst

The presented study aims to improve the quality of bio-oils by catalytic upgrading of pyrolysis bio-oil from microwave pyrolysis of biomass using transition metal modified activated carbon (AC) catalyst. A central composite experimental design (CCD) was used to optimize the reaction conditions for high quality bio-oil production. The effects of reaction temperature and reaction time on product ...
